HDMI ARC and eARC are very common terms in regards to home audio. ARC stands for audio return channel. It basically sends audio in the "opposite" direction down an HDMI cable.

However, HDMI ARC is very limited in the amount of data that it can transfer. For high quality and complex audio systems, it has to compress the audio signals in order to transfer them completely.

HDMI eARC fixed this by increasing the amount of data that it can transfer tremendously!
